Description

This sequence change creates a premature translational stop signal (p.Gln699*) in the PKP2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PKP2 are known to be pathogenic (PMID: 15489853, 23911551). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with arrhythmogenic right ventricular cardiomyopathy (PMID: 15489853, 23514727). ClinVar contains an entry for this variant (Variation ID: 2137311). For these reasons, this variant has been classified as Pathogenic.
